GUIDE MACHINE cenromu TION, on NEW YORK, N. Y., A conromrronor NEW YORK SPOOL HOLDER FOR FUR-SEWING MACHINES Application filed July 23,

This invention relates to sewing machines, and particularly to a spool holder for a fur sewing machine, although it is not necessarily limited to use with this type of machine, and has for an object to provide an improved spool holder which will permit quick change from one colored thread to another and facilitate the replenishing of the thread when one spool is exhausted, and in which after one spool is exhausted a new and filled spool may be substituted therefor with a quick and simple operation, thus greatly reducing the time the machine must be stopped for changing the thread or for renewing the thread. X

With the foregoing and other objects in view the invention consists in certain novel features of construction, combinations and arrangements of parts as will be more fully described in connection with the accompanying drawing. In this drawing,

Fig. 1 is a side elevation of a fur sewing machine with my improved spool holder applied thereto, a portion of the spool and its support being shown in section.

Fig. 2 is a top plan View of the holder.

Fig. 3 is a detail section substantially on line 33 of Fig. 1, and

Fig. 1 is a section substantially on line 4-4 of Fig.1.

The frame of the machine is indicated at and has the usual horizontally reciprocating needle and cooperating looper, not shown. At the top of the cover 11 is mounted the tension and guide 12 for the thread 13 taken from a spool 14. An improved support for'this spool comprises a head having a a body portion 15 and two or more branches 16 extending laterally from the body portion, preferably adjacent the upper end thereof. The body portion 15 has a socket 17 opening through the lower end thereof to receive the end of a supporting rod 18, and a spring 19 in the socket engages at its opposite ends the bottom of the socket and the end of the rod and tends to force the rod outwardly. The body portion 15 has an elongated slot 20 in its side wall which has recesses 21 and 22 at its opposite ends in the lower wall of this slot. The rod 18 carries a pin or screw 23 1928. Serial No. 294,812.

which. projects intoth-is slot and may seatin the recesses2'1 and 22 and cooperatewith the. a'cti-ontof the spring 19 to hold the head in different positions.

1 Each of the branches. 16 carries a. support for the spools 1d and 14:. In the form shown. it comprises a stud 2a inserted in the branch and threaded: at 25 to be threaded into the opening 26 in the center of the spool. Thus the spool may be applied to the head by merely screwing it onto the threaded portion: 25, and it may be easily removed therefrom.

The rod 18 is secured to the frame of. the machine by any suitable means, such as a bracket 27/, secured to the rear wall of this frame by any suitable means, such as screws 28. The bracket has asocket portion. 29. to receive the end of the rod 18 and in which it may be secured by any suitable means, such as a transverse pin 30;.

The operation is asfollows: Assuming the head is in the position of Figs. 1. and 2,, the thread is being taken from the spool 14,. the spooll4 carrying a different colored thread or being in reserve. If'it is desired'to usev the other colored thread or as soonas the spool14 is exhausted the operator or assistant merely presses-downwardly somewhaton top of the head. 15 which will remove the screw or pin 23. from the recess 21. The head may then be swung to the left or counterclockwise, as The head. will beheld in this position by the dotted lineposition and the spool 14' tothe position. formerly occupied by the spool 14. The. head will beheld inthisposition by the pinor screws 23 seating in therecessf22-i The thread may now be taken from the spool 14", and if desired while this is beingdone ifthe spool l isempty may be removedand a filled spool. mounted in its place, or a spool havin differently coloredithreadimay be substitute The head may be swung backto its original position. by a similar operation to the one described, bringingthe new spool'to the position for supplying the thread. This would, if desired, also permit removal of' the old spool 14" and the substituting of a new spool therefor.

It will be apparent that this is a very simple arrangement and thatwhen a difi'erently colored thread is desired or when one spool is exhausted, a new spool may be brought to its position with a simple and a quick movement. Also that while the machine is running an empty spool may-beremoved by an assistant 7 and a new filled spool mounted'in its place.

' Both of these features reduce the time required for changing the thread or renewing 10 thread when a spool is exhausted,and-g'reatly f decreases the time the-machine must be stopped for these'purposes, thus increasing production. Having thus set forth the; natureof my invention, what I claim is 1. A spoolholder forsewing machines including a support, ahead mounted for lim ited turning movement on said support, a

I plurality of spool holders on said head arranged with their'axes at an angle to each other so that turning said head may bring either spool to the operative position, and means yieldingly retaining the head in different positions. r A

[2, l A spool holder for sewing machines including a supporting rod, a head having a i I socket to receive said rod and capable of limited turning movement thereon, a spring tending to-force the head longitudinally of.

the rod'and cooperating means on the socket androd' for yieldingly holding thehead in diflerent positions under action of said spring, and a plurality of spool holders on V ent positions or the-head.

3. A spool holder for'sewing machines insaid head arranged to supporttheir respective spools in operative position in the differcluding a supporting i'oda head havinga socket to receive the end'of said rod and providedwith an elon ated slot in its side wall leading to said soc et having recesses adj a-' cent the opposite ends thereof, a pin on the rod e'xtendinginto said slot, a spring in the socket tending to force the rod outwardly and retain the pin in. one of said recesses, and a pluralityofspaced spool holders on the head arranged to extend outwardlytherefrom.

. 4. Aspool' holder sewing machines includinga supporting rod, means'ifor securng sa drodtothe frame'of a machine, ahead 1 havin'g'asocket to receive the upperend of th'ejrod and having an elongated slot in its sidewall leading to saidsooket provided with recesses at its opposite ends, a pin in the rod extending into said slot and capable of seat ing in said recesses, a spring in the socket tending to separate therod and head,

branches on the head extending laterally therefrom in different directions, and studs on said branches to support the spools.

. In testimony whereof I aflix my signature.
